Custom manufacturing in China
PartVerity coordinates requirement closure, process-fit supplier selection, production gates, inspection evidence and delivery through a European project interface operated by Kopintra Industrial Group.
Commercial fit
The model is most useful when manufacturing decisions must remain connected to revisions, measurable acceptance criteria and a defined delivery basis. It is not positioned as a universal buying route for every part.
Custom parts defined by CAD, drawings, samples or controlled specifications.
Prototype, low-volume or repeat production requiring a visible technical decision trail.
Projects where material identity, critical features, tooling, inspection or supplier choice affect usable outcome.
European engineering and procurement teams that want one accountable coordination point.
Catalogue products that can be bought more efficiently from an authorised distributor.
Requests without sufficient product definition or authority to resolve contradictory requirements.
Projects selected only on the lowest initial price while excluding required inspection, documentation or change control.
Regulated or safety-critical work where the required approvals, certifications or qualified process chain cannot be demonstrated for the specific project.
Responsibility matrix
PartVerity coordinates the project and evidence flow; the customer retains product-design authority and the selected manufacturing partner executes the released production route. Project-specific commercial agreements remain controlling.
| Stage | Customer | PartVerity project control | Manufacturing partner |
|---|---|---|---|
| Product definition | Design intent, approved drawings and functional priorities | Clarify contradictions and control the accepted RFQ basis | Review manufacturability against the released definition |
| Manufacturing route | Approve material or process changes | Compare route and supplier fit; document assumptions | Propose and execute the agreed process |
| Production | Respond to agreed technical decisions | Track milestones, revisions and approved changes | Manufacture to the released project basis |
| Inspection | Identify critical characteristics and acceptance needs | Align evidence to the inspection scope and review release status | Measure, record and contain non-conforming output |
| Delivery | Confirm destination and receiving constraints | Coordinate release information and shipment handover | Pack and provide agreed production documentation |
Project gates
The exact evidence and approval authority depend on the drawing, process and commercial agreement. These gates provide the control spine for the project.
Models, drawings, revision, material, quantity, finish, inspection and delivery basis are reconciled before supplier release.
The manufacturing route is matched to geometry, material, tolerance, volume, validation needs and the supplier's relevant process capability.
Quotation scope, exclusions, tooling, documentation, logistics basis and change assumptions are made visible before an order is placed.
Open DFM items are closed and the accepted revision is identified before production or tooling work is authorised.
Requested evidence is reviewed against the agreed plan. A report is not treated as acceptance when it omits a critical characteristic.
Shipping documents, packaging basis, outstanding deviations and repeat-order information remain linked to the project record.
Risk-control rules
No silent material substitution
No production against an obsolete revision
No automatic release because parts are complete
No tolerance promise without feature-level review
No factory claim accepted without project-relevant evidence
No change hidden inside an email chain
Process routes
Each commercial owner page explains the process-specific DFM, material, tolerance, inspection and timing considerations. The RFQ route remains shared so multi-process projects do not fragment.
